Any card using the Broadcom 43xx chipset
From MEPIS Documentation Wiki
The native driver for Broadcom 43xx cards and winmodems usually interferes with normal operation of wlan0 (Ndiswrapper). If it does (often just works in MEPIS 6.5). it needs to be blacklisted.
- You need to edit a file with superuser permission. The easiest way for beginners is to use File_Manager_-_Super_User_Mode
- Enter /etc/modprobe.d/ in the address bar, click open, then open the file "blacklist"
- Add these lines (including a remark such as the one below to indicate why you are doing this):
# Interferes with wlan0
blacklist bcm43xx
- Save and exit.
- Then go to MEPIS Utilities or MEPIS Network Manager/Assistant and follow the directions.
Sometimes it helps to remove the all drivers and then reinstall the one for your card.
ndiswrapper -e <all drivers, one at a time>
Use ndiswrapper to install the broadcom driver from scratch (your oringinal driver software), then as root do "modprobe ndiswrapper." Configure wlan0 with essid and key, if any.
Note: this chipset will also block the operation of knetworkmanager with unencrypted networks, leaving the application hanging at "28%." This is a known bug, see this Ubuntu discussion
